C++ c_str() function along with C++ String strcpy() function can be used to convert a string to char array easily. The c_str() method represents the sequence of characters in an array of string followed by a null character ('\0'). It returns a null pointer to the string.

You use CString::GetBuffer() to get the TCHAR[] - the pointer to the buffer. If you compiled without UNICODE defined that's enough - TCHAR is same as char, otherwise you'll have to allocate a separate buffer and use WideCharToMultiByte() for conversion.
